Abstract

An electrical connector (1) comprises an insulative housing (2), a number of terminals (3) received in the housing and a shell (4) enclosing the housing for electromagnetic interference protection. The housing has a number of grooves (242) defined in longitudinal walls (204) and a pair of projections (25) formed on lateral walls (206). The shell comprises a number of tags (42) secured in the grooves, a pair of downwardly extending board locks (44) interfering with the projections, and a number of tabs (45′) integrally extending from lateral walls (412) thereof to engage with recesses (29′) of the housing.

Claims

1. An electrical connector comprising:

an insulative housing having a pair of projections formed on opposite ends thereof, each projection having an outer head and an inner neck;

a plurality of terminals retained in the insulative housing; and

a metal shell enclosing the insulative housing and comprising a pair of downwardly extending board locks, each board lock having a pair of spaced legs straddling the neck and abutting against the head of a corresponding projection;

wherein the neck is generally of a T-shaped configuration and has a large-dimensioned upper portion and a small-dimensioned lower portion, and wherein the board lock has a pair of inwardly extending barbs formed on inner sides of the spaced legs for latching beneath the upper portion and interfering with the lower portion of the neck;

wherein the housing defines a receiving cavity through a mating face thereof, and wherein each terminal includes a mating portion disposed in the receiving cavity for engaging with a corresponding terminal of a complementary connector;

wherein the housing defines a plurality of recesses in communication with the receiving cavity, and wherein the shell comprises a plurality of spring arms aligned with the recesses and extending downwardly into the receiving cavity;

wherein the housing defines a cutout in communication with the receiving cavity for engaging with a corresponding projection of a complementary connector;

wherein the housing comprises a protrusion disposed below the cutout, and the protrusion defines an aperture therein;

wherein the shell comprises a body portion and a pair of opposite end portions, each end portion including a downwardly extending extension, and the extensions being inserted in the aperture of the protrusion and closely abutting each other;

wherein the extensions have a plurality of barbs for interference fitting with the aperture of the insulative housing;

wherein the insulative housing defines a pair of grooves in communication with the receiving cavity, and wherein the shell comprises a pair of downwardly extending tags adjacent to the extensions for being secured in the grooves;

wherein the insulative housing defines another groove opposite to the cutout, and wherein the shell comprises another downwardly extending tag opposite to the extensions for being secured in the groove;

wherein the housing defines a plurality of outwardly exposed slots, and wherein the shell comprises a plurality of inwardly extending tongues for engaging with the slots;

wherein the housing has a plurality of protrusions, and wherein the shell has a pair of bottom edges abutting against the protrusions;

wherein the insulative housing defines a plurality of recesses on a mounting face thereof, and wherein the shell comprises a plurality of tabs integrally formed on opposite ends thereof and bent inwardly for being received in the recesses.
